【摘要】：绞车是钻机的八大核心部件之一,绞车在钻井过程中,不仅担负着起下钻具、下套管、控制钻压、处理井下事故、提取岩芯筒、试油等各项作业,而且配套在陆地钻机上,还担负着井架和底座的起放任务。新型7000米交流变频两挡绞车设计为可满足海洋、沙漠、山区等复杂环境下7000米井深钻井作业的要求,该类型绞车操作简单、结构紧凑、维修便利,市场需求量大,前景广阔。本文分析并研究了现阶段国际及国内的绞车设计制造概况,结合钻机绞车日常使用需要及客户需求,意在设计研制一款操作简单、结构紧凑、维修便利的钻机绞车。本文JC70DB两档绞车设计为整体、单轴。由两台高速、宽频、大扭矩的交流变频电机通过球笼式万向联轴器和双减速箱联结,经两档斜齿减速箱带动滚筒轴。主刹车采用两侧、双盘风冷式液压盘式刹车,与电机能耗制动组合,通过钻机电控系统获得制动扭矩,来实现零速悬停。另外在绞车的减速箱输入侧另一端由一台45kW交流变频电机通过离合器传动齿轮箱,即可实现自动送钻,还可在紧急情况下提起最大钻柱重量。JC70DB绞车主要由滚筒轴、左右齿轮箱、电机、滑移式球笼等速万向联轴器、自动送钻装置、绞车架、润滑系统等组成。绞车整体结构紧凑、安装维护方便。
[Abstract]:Winch is one of the eight core parts of the drilling rig. During drilling, the winch is not only responsible for drilling tools, casing, controlling drilling pressure, handling downhole accidents, extracting core tubes, oil testing and other operations, but also supporting on land drilling rigs. It is also responsible for the lifting and setting-up of the Derrick and the pedestal. The new type of 7000 meter AC frequency conversion double-gear winch is designed to meet the requirements of 7000-meter well deep drilling in complicated environment such as ocean, desert and mountain area. The winch has the advantages of simple operation, compact structure, convenient maintenance, large market demand and broad prospect. This paper analyzes and studies the general situation of the design and manufacture of the winch both at home and abroad at present. Combined with the daily use needs and customer requirements of the rig winch, the purpose of this paper is to design and develop a drilling rig winch with simple operation, compact structure and convenient maintenance. In this paper, JC70DB two-gear winch is designed as a whole, single axle. Two high-speed, wide-frequency, high-torque AC frequency conversion motors are connected by ball-cage universal coupling and double reducer, and the roller shaft is driven by two-gear helical gear reducer. The main brake adopts double-disc air-cooled hydraulic disc brake, which is combined with the motor energy consumption brake. The braking torque is obtained by the electric control system of the drilling rig to achieve zero-speed hovering. In addition, at the other end of the input side of the reducer of the winch, a 45kW AC variable frequency motor is used to drive the gearbox through the clutch, so that the automatic drilling can be realized and the maximum weight of the drill string can be lifted in emergency. The JC70DB winch is mainly driven by the roller shaft. Left and right gearbox, motor, sliding cage constant speed universal coupling, automatic drilling device, winch, lubrication system, etc. The whole structure of winch is compact and easy to install and maintain.
